*SPIRIT UPDATE: Spirit Analyzing 'Keystone' - sol 462-470, May 03, 2005
Spirit is in excellent health. The rover has spent this week (April 22
to April 30, 2005) studying an outcrop called "Methuselah," focusing on
the "Keystone" rock. Before Spirit drives away next week, it will have
analyzed this feature with every tool in the science payload.
*Sol-by-sol summaries:*
Sol 462 (April 22, 2005):
Spirit drove 3.8 meters (12.7 feet) to reach a place to stop for the
weekend and perform remote sensing.
Sol 463:
Spirit performed light remote sensing to save space in the flash memory
for the weekend.
Sols 464-466:
Spirit took extensive imaging of Methuselah. It used its panoramic
camera to shoot frames that will be joined together into a mosaic view.
Spirit also took images with its miniature thermal emission spectrometer
and made atmosphere observations.
Sol 467:
Spirit did a 4.75-meter (16-foot) drive to Keystone, a rock that is part
of the Methuselah outcrop. The rover also used its miniature thermal
emission spectrometer to examine a target informally called "Abigail."
Sol 468:
Spirit used the panoramic camera and the miniature thermal emission
spectrometer to takes images of Abigail and another target called
"Priscilla."
Sol 469:
Spirit took pictures of Keystone with the microscopic imager and
performed an overnight alpha particle X-ray spectrometer integration on
Keystone.
Sol 470:
Spirit finished acquiring mosaic pictures of Keystone with the
microscopic imager, dusted the target with the rock abrasion tool brush,
and performed another overnight alpha particle X-ray spectrometer
integration.
As of sol 470 (ending on April 30, 2005), Spirit's odometry total is
4,310.68 meters (2.68 miles).

*OPPORTUNITY UPDATE:
Testing on Earth Before Moving on Mars - sol 449-455, May 06, 2005
Opportunity is imaging the plains and performing atmospheric science
observations while waiting for engineers on Earth to give it the
go-ahead to move. The team is diligently working to determine why
Opportunity dug itself into a small dune, the best way to exit the dune,
and what added precautions to use during future driving.
*Sol summary:*
Sols 449 to 455 (April 29 to May 5, 2005):
In JPL's In-situ Instrument Laboratory sandbox, engineers, scientists
and even the project manager have been mixing sandy and powdery
materials, digging holes and building dunes. A mixture was concocted to
simulate properties of the soil underneath Opportunity, using sand, clay
and diatomaceous earth (silica-rich powder composed mainly of
microscopic plant shells, used in these tests for its texture, not its
fossil origin). The team wants to have a full understanding of how
Opportunity will respond before commanding it to back out of its current
position.
